The Smartest/Dumbest Hostage

With your hand in your pocket, you finger the trigger of your gun as you approach the entrance to the bank. Walking in, you pass a number of large security guards and notice some cameras eyeing you as well. Sweat is trickling down your forehead as you approach the bank-teller. "How may I help you?" she asks you in a calm, almost happy voice. You open your mouth, but your tongue is dry and swollen. Just as you are about to stuff the barrel of your gun in her mouth, the doors to the front of the bank burst open and shots are fired. Five very proffessional looking man with AK-47's enter the room and pump some lead into the security guards chest, blood spraying from the wound and pooling onto the floor.
